Automated bitcoin arbitrage

[DobZombie]

right, the latest commit does this when the arbitrage program wants to trade

Code:

I'm stuck finding the error (help)

Hmm, the bot immediately closes if I include either SpecializedTraderBot or TraderBot, but not if TraderBotSim is included. Also, when trying to include BTC-e, the bot says

Code:

"[WARNING] Can't automate this trade, client not available: BTC-e

Though, upon viewing the TraderBotSim file code, I notice it doesn't fully include BTC-e support. I'll keep looking into it.

Someone earlier asked about inter-market trading. Any plans to support that in later releases?

[maxme]

The private part of BTC-e API is not implemented _yet_

[maxme]

I pushed a new feature: fiat currency mixed trades. Now you can buy on market X with EUR and sell on market Y with USD.

Note: Fiat rates conversion are updated every hour from http://rate-exchange.appspot.com/

Is anyone getting an error like this?

Code:

I did remove my mtgox key but when i run the program the key shows up fine.

Is there no way to transfer funds between exchanges? Otherwise why would it be beneficial to buy low on one and sell high on the other?

[maxme]

You may:

• withdraw funds from an exchange and deposit to an other exchange (manual and long operation, painful, cuts profits with fees)
• wait for a counter operation and buy low on the exchange you sold previously
• use other currencies (ltc for instance)
• wait for an equilibrium and do a negative operation only to transfer funds from one exchange to another (cuts profits of course)

[JstnPwll]

Hmm. It seems like the most automatic method would be to code it so that when there's an equilibrium, both accounts trade out some of the currency they have been selling for the currency they've been buying. Like you said, it would cut profits (especially with trade fees), but that might be better than stagnating and missing good trade opportunities.

P.S. Thanks for the code! I'm having fun looking at it.

just trying to run

but getting this error, I believed i configured correctly and was using the tradersim  to test

[Ianwhitbread]

Well, I could trade on MtGox in BTCUSD and BTCEUR if I know EURUSD (or assume EURUSD as static - compared to BTC that might even be true)...

If there's a plugin for other "real" Forex brokers that might even work quite well! Still it might be enough to do fiat trades in bulk after some time, as the volatility is quite different there. Hence it might be possible to trade two currency pairs on the same "market".

U will never make money arbing a forex broker. If u trade against broker u will be banned and id u trade against the bank u will get last looked to death.

Greetings!

Just found this tool out.

It's great!

Just some suggestions for TODO:

* Add Triangular Arbitrage calculator and automated arbitrage implementation of it: as previously said - "This can be done in a single exchange";

* Add automated arbitrage for altcoins pairs (LTC/BTC; NMC/BTC; PPC/BTC; XPM/BTC etc.);

* Add support for exchanges with medium volume and various cryptocoins (such as Vircurex and Cryptsy);

Ps.: forget Ripple support...  

BTW, here goes some codes and other similar ideas in order to get some insights:
